Two year old hen, hasn't laid in a long time. Bright eyed, comb and wattle nicely red, eating and drinking well. However, she has a loss of feathers on her neck which we thought was feather pulling but when I picked her up to look, she had these large growths on her skin almost looking as if they are coming out of the feather follicles. Now she has one under her wing which is about 5 cm in diameter at the base and at least as tall, shaped like a cone and hard at the top. It moves freely from the tissue under the skin, is not bleeding or oozing anything - but what is it and how do I treat it? Other than this, she seems really well! Here are some photos! Hope someone can help. Thanks.
